All great scientific solutions start with collaboration

KNOXVILLE — The challenges facing the planet and its inhabitants have long been too complex for any one individual or group to address, and that’s why the great advancements in modern science begin with conferences, symposiums and collaboration.

The first Environmental Future Symposium is an effort from the University of Tennessee Office of Sustainability to present a vision of the future for area residents and University of Tennessee students. 

Planned for the Agriculture and Natural Resources Ballroom and Plaza from 2 p.m. to 6 p.m. March 27, the symposium is spearheaded by the office’s Alternative Energy and Transportation Coordinator Ben Gouffon. His vision for the event is simple: at the intersection of human-accelerated climate destabilization and a revitalization of the collapsing biosphere sits every individual and their  actions. His hope is that this symposium is an avenue for every attendee to discover what they can do for Knoxville, the university and the planet they call home.

KNOXVILLE — The Tennessee Department of Environment and Conservation granted $350,197 to the University of Tennessee from the Tire Environmental Act Program. 

“We are seeing great advances in repurposing tires for environmental benefits,” said TDEC Deputy Commissioner Greg Young. ”Programs like this not only help clean up sites of used tires, they involve innovative new uses for them. We congratulate UT-Knoxville on this project.”

UTK is partnering with the Tennessee Department of Transportation (TDOT) to install a series of pavement test sections using the technologies developed from this project. Benefits of including rubber in asphalt pavement mixes include improved skid resistance, cracking resistance, and noise reduction.

The purpose of the Tire Environmental Act Program is to select and fund projects that best result in beneficial uses for waste tires. Projects must qualify for one of three categories: tire processing/recycling, tire-derived material use, or research and development. The program provides grant funding to eligible entities, including local governments, non-profit organizations, higher education institutions, K-12 schools and for-profit businesses.

Tennessee established the Tire Environmental Fund in 2015. Upon the first retail sale of a new motor vehicle to be titled and registered in Tennessee, a flat fee based on the number of a vehicle’s wheels is assessed. The fee goes into the fund, which is used for projects creating or supporting beneficial end uses for waste tires.

Since 2015, grantees have been awarded almost $6.8 million, and approximately 5.5 million tires or nearly 58,000 tons of scrap tires have been diverted from landfills. The tires are repurposed for use in rubberized asphalt, tire-derived aggregate, tire-derived fuel, granulated rubber porous flexible pavement, and other beneficial end uses that result in tires being diverted from landfills for a higher and better use.
